Network requirements
As shown in
•
IGMPv2 runs on Layer 3 device Switch A, and IGMPv2 snooping runs on Layer 2 device Switch
B.
•
Switch A acts as the IGMP querier.
•
The multicast source sends multicast data to multicast group 224.1.1.1. Receivers Host A, Host
B, and Host C belong to VLAN 2, VLAN 3, and VLAN 4, respectively.
Configure a sub-VLAN-based multicast VLAN on Switch B to meet the following requirements:
•
Switch A sends the multicast data to Switch B through the multicast VLAN.
•
Switch B forwards the multicast data to the receivers in different user VLANs.
